MECHANICAL TOY.

SPECIFICATION forming part of Letters Patent N o. 369,623, datedSeptember 6, 1887.

Application iiled February 2l, 1887. Serial No. 228,354.

To all whom it may concern:

Be it known that We, FRANCIS J. TOTTEN and ALBERT S. TorrEN, ofPittsburg, in the county of Allegheny and State of Pennsylvania, haveinvented a new and useful Improvement in Mechanical Toys; and we dohereby declare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, forming partof this specification, in which- Figure l is a vertical central sectionof our improved toy. Fig. 2 is a plan view thereof, the top board of thetoy being partly broken away to illustrate the clock-work mechanism.Fig. 3 is a side view of a part. Fig. 4 is a sectional view of amodified form of a part.

Like symbols of reference indicate like parts in each figure of thedrawings.

In the drawings, 2 represents a box or case of cylindrical form. The topof the box is covered, there being an annular rim or coverstrip, 3,around the edge of the box, and a central circular cover, 4, somewhatseparated from the ring 3, so as to leave an intervening circular slot,5. The parts 3 and 4 are held together by arches 6, which span the slot5. Inside the box 2 is clock-work mechanism comprising a spring, 7, akey-arbor, 8, and a vertical shaft, 9, which is driven by the spring.From the shaft 9 projects a horizontal arm, 10. A suitable toy, 11,mounted on Wheels, is set on a circular track on top ofthe box 2, and isprovided with a vertical stern, I2, which extends down through the slot5 into the interior of the box. When the shaft 9 is driven byclock-work, it causes the radial arm l0 to move around in the box, andby engaging the rod 12 causes the toy-cars l1 to travel around on theirtrack beneath the arches.

We are aware that we are not the first to invent a toy wherein a rotaryclock-workdriven arm drives a vehicle around on a cir cular track, norare we the first 4to use the arches 6, which serve to connect the partsof the top rigidly together without interfering with the slot. 1

Ourinvention consists of mechanism whereby the motion of the toy can beretarded or checked at will. Connected with the shaft 9 so by suitablegear-wheels is a vertical shaft, 13,

on which is a small drum,'14. A flexible band, 15, is secured at one endto a post 16, and after enwrapping or partially enwrapping the drum 14is attached to the free end of a lever, 17, which is fulcrumed at apoint, 18. At the point of attachment with the band 15 the lever 17 isbent and extends to the outside of the box 2 through an elongated slot,19. On the outside of the box is an upright lever, 20, which is pivotedat 21, and at itslower end is connected with the lever I7. By turningthe lever 20 on its pivot 2l the lever 17 is turned on its pivot 18, andin this way the band l5 may be caused to exert a pressure of a greateror less degree upon the drum 14. By exerting a greater pressure on thedrum the movement of the clock-work may be stopped altogether, and by aless pressure it may be retarded. In order to provide means for enablingthe lever 20 to be locked at any position when the desired tension ofthe band is obtained, we provide the lever with a rack or quadrant, 22,making in it a series of holes. A longitudinally movable latch, 23, isarranged on the side of the lever, and is movable to engage any one ofthe holes of the quadrant when the lever 20 is opposite thereto.

In Fig. 4 we show a modified form of device for braking the drum 14.I'Iere the band 15 is attached to a screw-rod, 24, which extends throughascrew-threaded bushing, 25, in the side of the box 2. By screwing therod 24 in or out the tension of the band ou the drum may be diminishedor increased.

We claim- 1. The combination of a movable toy mounted on a circulartrack, stationary clockwork, a rotary arm driven by the clock-workanddriving the toy, and braking mechanism bearing on the clock-work foradjustably retarding the motion thereof, substantially as and for thepurposes described.

2. The combination of a movable toy mounted on a circular track,clock-work mechanism ilnpelling the toy, the drum 14, connected with theclock-work, and the brakeband 15, enwrapping the drum, substantially asand for the purposes described.
